A filter tow blooming jet device for applying an additive to a continuous, multifilament filter tow is disclosed wherein the jet device is provided with orifice means transversely positioned in an elongated passageway through which the advancing filter tow passes and the additive is applied by nozzle means concentrically positioned with respect to the advancing filter tow at a point downstream of the orifice means. The additive may also be applied to the filter tow by nozzle means positioned adjacent to the wall surface of the elongated passageway or by injecting the additive into a stream of gaseous fluid introduced into the jet device for blooming the filter tow.
